CEMENTING MACHINE Filed Nov. 6, 1929 ,Ziiven?or,

Patented July 14, 1931 UNITED STATES PATENT OFFICE CARLOS 1a. BOWLEN, OFHAVERHILL, MASSACHUSETTS, ASSIGNOR To IRVING L. KEITH,

OF HAVERHILL, MASSACHUSETTS I GEMENTING MACHINE This invention relatesto cementing machines which areprimarily designed for use in cementingsock linings to the bottoms of shoes, and particularly to machines ofthe type disclosed in my prior Patent #1,565,-

- 004, dated December 8, 1925.

lVhile machines constructed as illustrated in my said prior patentoperate satisfactorily in cementing sock linings in shoes of certaintypes, in certain other types of shoes, and more particularly thosehaving high heels, considerable difficulty has been encountered inperforming this work satisfactorily, for the reason that transversewrinkles or pockets are liable to be formed in the lining between thetransverse strips of adhesive which are applied by the bars. That is,the uncemented portions of the lining between the cemented strips arenot held in close contact with the shoe bottom, but tend to rise up fromthe bottom in ridges. This difliculty is not likely to occur in the heeland foreparts of the bottom, or in the rear portion of the shank part,but is particularly likely to occur in the front portion of the shankpart closely adjacent the ball line, at whichline the shoe if it carriesa high heel, is bent so sharply that a relativelydeep transverseconcavity is formed, which is often deeper in the middle portion than atthe sides of the shoe.

The object of my present invention is to provide a form of grid whichwill apply the cement to the heel and forepart of the lining insubstantially the same manner as disclosed in said patent and willenable these portions to be secured in position in a manner which issatisfactory, and which will also apply the cement to the shank portionin such a manner that the lining when inserted in the shoe, and pressedagainst the bottom, will be held closely to the bottom surfacethroughout, so that no wrinkles or pockets will be formed between theportions which are adhesively connected and those which are not.

I accomplish this object by providing the grid with a series oftransverse bars which are so arranged that transverse stripes of cementwill be applied to the heel and foreparts, as in my said priorconstruction, and with intermediate longitudinal bars, so thatlongitudinal stripes of cement will be applied to the shankpart of thelining or portions adjacent the ball part thereof.

For a more complete disclosure of the invention, reference is made tothe following specification in connection with the accompanying drawingsin which:

Fig. 1 is a plan View of a cementing grid embodying my invention.

Fig. 2 is a transverse section thereof, at line 22 of Fig. 1 and Fig. 3is a side elevation thereof.

The grid herein disclosed is supported, operated and in a general wayconstructed, identically as disclosed in my said patent and comprisesend hangers a between which parallel supporting rods Z) are extended,means being provided for holding said rods horizontally and for loweringthe same into a cement pan and for lifting it above the liquid level. YA parallel series of suitably spaced, transversely disposed cementingbars 0, (Z are mounted on the end portions of the rods Z), a suflicientnumber thereof being provided to form a cementing surface at each end ofthe grid which extends lengthwise of the grid a distance approximatelyas great as the length of the forepart of any sock lining which islikely to be placed thereon. The bars shown are preferably of the zigzagtype, although they may be straight, or otherwise formed, and their topedges are longitudinally convex, the structure being, as thus farreferred to, substantially the same as in my said prior patent.

According to my present invention, a pair curved surface as that of thetop edges of the bars 0, (Z. Also the holes, or recesses in the bars 6,in which the round bars are mounted, are formed close to the top edgesthereof, so that the surfaces of' the round bars are practically tangentto thesame curved surface as that in which the top edges of the otherbars lie.

In using the device for cementing sock linings, the grid will besubmerged in'liquid cement and then lifted above the level thereof, andthen thelining will be placed lengthwise of the grid insuch a positionthat its shank portion rests on the longitudinal bars f and itsforepa-rt rests on one of the sets of transverse bars 0 or (Z, the heelpart resting onthe other set of transverse bars,

approximately as indicated in Fig. 1.

As' a result of this operation transversely extending stripes of cementwill be applied to the fore and heel parts of the lining andlongitudinally extending stripes of cement will be applied to the shankportion thereof, said stripes conforming to the formation of the gridportion to which the lining is applied. In practice, some or all of thelongitudinal stripes will preferably extend for a short distance acrosswhat is usually considered as the ball-line, so that, when the lininghas been placed in positionin the shoe and pressed into contact with theshoe bottom throughout its entire surface, by means of a brush or othermeans, this operation being performed in the manner described in saidprior patent, the lining will be adhesively connected to the shoe bottomthroughout its entire surface, and the portion of the lining adjacentthe ball line will be connected by stripes of cement which extendlongitudinally of the shoe, or trans versely of the concave portionformed by the bend at the front end of the shank. As these stripes ofcement thus run crosswise of this concavity, the lining will beconnected to the shoe bottom along these stripes and the formation oftransverse wrinkles or pockets in the lining will be prevented, theuncemented portions being held fiat on the shoe bottom. The otherportions of the lining will be effectively attached by the transversestripes of adhesive, the shank portion in the rear of the concaveportion at the ball being as effectively held by the longitudinal, as bythe transverse stripes of cement. It will be understood that if thelinings were always to be placed on the grid with the toe end at thesame end of the grid,

" the bar arrangement would probably be changed somewhat from thearrangement shown, but it is desirable to be able to place the lining onthe grid with the toe portion at either end, so that the arrangementshown is considered to be the more advantageous.

It will be understood that the particular types of bars shown are notessential to the invention, although they are preferable.

I claim:

1. A grid for applying a liquid adhesive to sock linings of shoescomprising two series of adjacently disposed" bars, the bars of bothseries having adhesive applying fa es at their top sides all disposed inapproxim'ately the same surface, the bars of one of said series beingarranged for engageinent' witli the forepart of the lining and the barsof the other series being arranged for engagement with the portion ofthe lining at and adjacent the line at which its shank part meets theforepart, the bars of the latter series being arranged to extend intransverse relation to said line to apply the adhesive to such portionin stripes which extend longitudinally of the lining.

2. A grid for applying a liquid adhesive to sock linings of shoescomprising two series of adj acently disposed bars, the bars of bothseries having adhesive applying faces at their top sides all disposed inapproximately the same surface, the bars of one of said series beingarranged for engagement with the forepart of the lining in transverserelation theretoand the bars of the other series being arranged intransverse relation tothe fore part engaging bars and iI1:POS1- tion toengage the portion of the lining adjacent the junction ofthe shank andforepart of the lining and to apply adhesive to such portion to stripeswhich extend lengthwise of the lining.

3. An elongated grid for applying liquid adhesive to sock linings ofshoes comprising two series of adjacently disposed bars having adhesiveapplying faces at their top sides arranged to provide a transverselyconvex cementing surface, the bars of one of said series being arrangedtransversely of the grid and the bars of the other series being arrangedlongitudinally thereof, each bar of the longitudinal series beingterminated in close proximity to the side of the adjacent bar of thetransverse series.

4:. An elongated grid for applying liquid adhesive to sock linings ofshoes comprising two series of transversely disposed bars arranged atthe opposite ends of the grid and an intermediate series oflongitudinally extending bars terminating at the sides of the adjacenttransverse bars, all of said bars having adhesive applying faces attheir top' sides arranged to provide an adhesive applying surfaceadapted to receive the fore part of the lining on one of said transverseseries of bars and the shank part thereon on said longitudinal series ofbars.

5. An elongated grid for applying liquid adhesive to sock linings ofshoes comprising two series of transversely disposed bars arranged atthe opposite ends of the grid and an intermediate series oflongitudinally extending bars mounted at their ends in the adjacenttransverse bars, all of said hars having adhesive applying surfacesarranged for simultaneous engagement with the lining When placedthereon.

In testimony whereof, I have signed my name to this specification.
